In-N-Out 10 

A girl who would not be considered a 10 under normal circumstances, but is a 10 due to the simple fact that she is in a fast food restaurant lobby where hot girls usually don't hang out.

Bro #1: Bro, check out that girl in the line that just ordered a double-double and fries!
Bro #2: Dude, she's a straight up In-N-Out 10!

In-n-out 

In-N-Out is a privately-owned hamburger fast food chain located in California, Arizona, and Nevada. It's simple menu has remained unchanged since the restaurant's extablishment in 1948. There are also "secret" item specials, variations of the basic menu that are not listed on the menu nor advertised.

In-N-Out's got the best goddamn burgers on the face of the planet.
